Noise control techniques for tires employing three different size design cycles

摘要

A tire (10) adapted to rotate around an axis and including a plurality of design cycles (19-34) extending circumferentially around the tire. The design cycles have a total of three different pitch lengths (S,M,L) that define a percent variation and a percent unbalance, the product of the percent variation and the percent unbalance lying in the range of 1,250 to 1,350.
